nepyope/Project-Homunculus
Project Homunculus is open-source, low-cost hardware for capturing human hand and arm motions. It has two parts.
It measures 72.1 × 39.4 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the ESP32-C3-WROOM-02-H4, DRV8833PW and AMS1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the DauntlessDog/The-Ant repository on GitHub, at the commit this page was made from: the board is TheANTPCBV1.kicad_pcb and its schematic TheANTPCBV1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
